Introduction
The TRX-PS-BU series of products are designed to supplement the Trinix
DV-33128, DV-33256 and DV-33512 internal power supplies to provide
increased backup protection.. Three packages are available:
• TRX-PS-BU1200 - 1 ea. 1200 watt module mounted in a 1 RU frame
• TRX-PS-BU2400 - 2 ea. 1200 watt modules mounted in a 1 RU frame
• TRX-PS-BU3600 - 3 ea. 1200 watt modules mounted in a 1 RU frame
Each module consists of a Unipower TPCP 7000 1200 watt power supply.
The rack frame is a Unipower TPCP R1U3-B 1.75-inch chassis.
As shown on the facing page, these packages can be used in various com-
binations with Trinix DV-33128, DV-33256, and DV-33512 routers.
The power supplies are essentially bussed together so that the power load
is shared at all times. If one supply fails, the remaining supplies on that bus
will continue to provide power. The failed supply should be replaced as
soon as possible.
DV-33128
For DV-33128 routers, installation of one TRX-PS-BU1200 will provide a
total of three on-line power supplies: two internally-mounted supplies and
one supply mounted in the external chassis. Any one of these three sup-
plies can fully power the DV-33128 router.
Installation of one
TRX-PS-BU2400 will provide a total of four on-line
power supplies: two internally-mounted supplies and two supplies
mounted in the external chassis. Any one of these four supplies can fully
power the DV-33128 router.
